In the Hitchhiker’s Guide, the supercomputer, Deep Thought, tells us that the answer to the ultimate question of life, the universe and everything is 42. Deep Thought pointed out that the answer seems meaningless because the beings who instructed it never truly knew what the question was.

However, I believe I have the question. I know that the question must be about belief & reason, faith & rationalism. Not any particular belief, say, the belief in the existence of God, but belief itself. Not any particular thought, e.g., that all unmarried men are bachelors, but thought itself.

In order to believe something, do we need to think that belief is necessary for getting at the truth of things? But that begs the question if belief is sufficient, then why is thought necessary?

And how can we trust our thoughts, unless we believe them to be trustworthy? Why do we accept it that rationalism is the way to search for meaning? Again, the dilemma: is it necessary to believe that thought is necessary in pursuit of truth?

So, the ultimate question could be which is the better way to probe for truth: through faith or via reason? But this fails as the ultimate question because it depends on a false dichotomy.

The question could be why do we have both at hand? No, this is too easily answered to be the ultimate question.

My question is the question that comes before all others, the single question of utmost importance to all humankind: are faith and reason together necessary & sufficient in the quest for the truth of life, the universe and everything?

are faith and reason together necessary & sufficient in the quest for the truth of life, the universe and everything?

Without some faith in reason itself, we could never say anything about anything. But that's where the role of faith ends, when it comes to a serious inquiry about life, the universe and everything. So actually both are necessary.

Are they sufficient? I don't think this can be answered. What if reality is actually "unreasonable", whatever that means? We may never know.
Even if reality is "reasonable", it can be modeled via reason, we may never see beyond the observable universe. All we can do is come up with all kinds of reasonable ideas and interpretations, and then argue which one is most likely.

Exactly so!

Now we need a new ultimate question.

Before we go there. I just want to add that to believe doesn’t require the thought that belief is a way to get at the truth of something. One only needs to believe that belief is a way to do so.

This takes nothing away from the claim that to begin inquiry, resson relies on the belief that reason is valid.
